Book Synopsis Reactions of Atoms and Radicals in Pulsed Molecular Beams by : H. Reisler

Available in PDF, EPUB and Kindle. Book excerpt: The final report describes studies of unimolecular reactions of transient species and radicals relevant to combustion processes. Specifically, the dynamics of predissociation of free radicals for which multiple pathways, including molecular rearrangements, compete. These small, prototypical, systems are amenable to treatment by high level theory, and close collaboration with theory continues to be a cornerstone of the program. The chemistry of hydroxyalkyl radicals is important in atmospheric and combustion environments, because cleavage of the C-H and O-H bonds is implicated in the reactions of several atoms and radicals with alcohols and alkanes. In particular, the hydroxymethyl radical affords many opportunities to study both isomerization and dissociation on the ground and excited potential energy surfaces. During this funding period, high vibrational levels of the ground electronic state of the hydroxymethyl radicals were accessed in two ways: (1) by using internal conversion from the lowest excited electronic state, the 3s Rydberg state; and (2) via direct vibrational excitation of the hydroxymethyl radical accessed by pumping OH overtones as ''bright'' states. In the former method, levels that are {approx} 3 eV above the H + formaldehyde asymptote are reached. In the latter, the region of the dissociation barrier is gradually approached from below, while examining the role of energy flow from OH overtones to other vibrational levels. The first task was to characterize the electronic absorption of the radical, in order to develop diagnostics and reach the ground state via excitation of the lowest-lying state, the 3s Rydberg state. To this end, excitations to the three lowest 3s and 3p Rydberg states were studied and the dissociation channels identified. These were predominantly O-H and C-H fission, while isomerization to the methoxy radical was not observed. Collaborations with theory identified the molecular dynamics on the excited electronic potential energy surfaces and how the ground state is reached via nonadiabatic transitions. Establishing the relevant dissociation and isomerization pathways on the ground electronic state requires studying energy flow patterns with increasing internal energy. Two energy regimes corresponding to distinct unimolecular dynamics were reached: (1) low energy spectroscopic studies of IR transitions in the region of the fundamental and first overtone of the OH-stretch, where intramolecular dynamics is likely to be weak and first manifested; (2) Studies of the region near the dissociation barrier, i.e. the third OH-stretch overtone, where dissociation occurs mostly by tunneling. The experimental approach relies on pulsed molecular beams, state-selective reactant preparation and product detection, and good resolution in both frequency and velocity domains. Radicals are prepared in molecular beams by using photoinitiated bimolecular reactions in a quartz tube attachment to the pulsed valve. Excitation is achieved using either overtone pumping of OH stretch vibrations, or excitation to an electrically excited state followed by radiationless transitions. Detection relies on time-of-flight methods with core sampling, which provide kinetic energy and angular distribution.
Book Synopsis Liquid-Phase Reaction Rate Constants by : E. T. Denisov
Download or read book Liquid-Phase Reaction Rate Constants written by E. T. Denisov and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 782 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past 25 years in chemical kinetics have seen major advances in studyiqg the mechanisms of complex chemical re actions, in particular free radical reactions. Many differ ent methods have been developed for quantitative studies of elementary chemical reactions. Thousands of rate constants have been measured, for hundreds of diverse chemical reac tions. It is becoming more and more difficult for the chemist to orient himself in the voluminous and rapidly growing liter ature of chemical reaction kinetics. This leads to major expenditures of time in searching out, collecting. and eval uating quantitative kinetic data; to unnecessary repetition (duplication) of research; and to a situation in which the rich material already accumulated in the field of chemical kinetics is very often not fully utilized in comparing, interpreting, and analyzing new experimental data. There is a pressing need for the creation of a series of handbooks on reaction rate constants. Such work was begun several years ago at the initiative of V. N. Kondrat'ev, and is now going forward under his direction at the Institute of Chemical Physics of the USSR Academy of Sciences. This book is devoted to liquid-phase, homolytic reactions. Part One contains data on monomolecular reactions in which molecules decompose to form radicals, as well as data on bi molecular and trimolecular reactions that form free radicals.

Book Synopsis The Mechanisms of Reactions Influencing Atmospheric Ozone by : Jack G. Calvert
Download or read book The Mechanisms of Reactions Influencing Atmospheric Ozone written by Jack G. Calvert and published by Oxford University Press. This book was released on 2015-05-13 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ozone, an important trace component, is critical to life on Earth and to atmospheric chemistry. The presence of ozone profoundly impacts the physical structure of the atmosphere and meteorology. Ozone is also an important photolytic source for HO radicals, the driving force for most of the chemistry that occurs in the lower atmosphere, is essential to shielding biota, and is the only molecule in the atmosphere that provides protection from UV radiation in the 250-300 nm region. However, recent concerns regarding environmental issues have inspired a need for a greater understanding of ozone, and the effects that it has on the Earth's atmosphere. The Mechanisms of Reactions Influencing Atmospheric Ozone provides an overview of the chemical processes associated with the formation and loss of ozone in the atmosphere, meeting the need for a greater body of knowledge regarding atmospheric chemistry. Renowned atmospheric researcher Jack Calvert and his coauthors discuss the various chemical and physical properties of the earth's atmosphere, the ways in which ozone is formed and destroyed, and the mechanisms of various ozone chemical reactions in the different spheres of the atmosphere. The volume is rich with valuable knowledge and useful descriptions, and will appeal to environmental scientists and engineers alike. A thorough analysis of the processes related to tropospheric ozone, The Mechanisms of Reactions Influencing Atmospheric Ozone is an essential resource for those hoping to combat the continuing and future environmental problems, particularly issues that require a deeper understanding of atmospheric chemistry.
